I think this is a very good decision. Tkinter may have less of a learning
curve but I don't think the control is there. The last project I worked on
used wxWindows (C++ version of wxPython) for some of the ui framework and I
found it very effective overall. We also used XML for ui specification, but
unfortunately only for specifying within a propietary widget system that ran
as a canvas on top of wxWindows frames. I'm guessing there must be a
standard XML parser for python also, no? I'll take a look at the python.org
site.
